take time from user !

Hi I have a gate and I want to take the time in and out from user but the problem in my program is saved as string see this

          %========= TIME IN==========%
          prompt = {'Enter Time In:'};
          dlg_title = 'TIME IN';
          num_lines = 1;
          defaultans = {'0'};
          TimeIn = inputdlg(prompt,dlg_title,num_lines,defaultans);

          %========= TIME OUT=========%
          prompt = {'Enter TIME OUT:'};
          dlg_title = 'Time out';
          num_lines = 1;
          defaultans = {'0'};
          TimeOut = inputdlg(prompt,dlg_title,num_lines,defaultans);

the problem here its store it as string and if the user enter let say 10:15 and out 10:50 how H can make sure that the interval between them is unavailable..

Parse out the numbers, like with strtok(), then pass the numbers into etime(). Or use newer functions like datetime().
